DIN EN 50549-10:2025-03

The purpose of this document is to provide technical guidance for tests on generating units and interface protection to evaluate their electrical characteristics. The evaluation results are intended to be used to demonstrate conformity of generating units to technical requirements for grid connection. It is possible that the conformity assessment of a generating unit does not cover all aspects of the above-mentioned standardization documents, typically when a requirement is evaluated on a plant level. Therefore, the conformity assessment report indicates clearly which clauses of this document are covered and which clauses are not covered. The standard differs from DIN EN 50438 (VDE 0435-901):2014-06 withdrawn in October 2020 as follows: a) the gaps in the conformity tests of EN 50549-1:2019 resulting from the replacement of EN 50438:2013 have been closed by the requirements for conformity testing of generation units contained in EN 50549-10. The assessment results can be used as part of a certification program.
